A Meta-Analysis of Genetically Modified Food Valuation Studies AgEcon
Lusk, Jayson L.; Jamal, Mustafa; Kurlander, Lauren; Roucan, Maud; Taulman, Lesley.
A plethora of research in recent years has been devoted to estimating consumer demand for genetically modified food, an important piece of information needed to create appropriate public policy. To examine this body of work, a meta-analysis was conducted of 25 studies that, in aggregate, report 57 valuations for GM food. Findings indicate as much as 89% of the variation in existing value estimates for genetically modified food can be explained by an econometric model that controls for (a) the characteristics of the sample of consumers studied, (b) the method for eliciting consumers' valuation, and (c) characteristics of the food being valued. Each of these factors has a statistically significant effect on estimated premiums for non-GM food. Results of...

CONSUMER PREFERENCES FOR QUALITY CHARACTERISTICS ALONG THE COWPEA VALUE CHAIN IN NIGERIA, GHANA AND MALI AgEcon

Cowpea fits the needs of the urban poor. It is an inexpensive source of protein that does not require refrigeration. A better understanding of consumer preferences for cowpea is essential to market development. The main objective of the study was to determine the cowpea grain quality characteristics that command a price premium or provoke a discount in Ghanaian, Malian and Nigerian markets. Specifically, the study looked at the impact of the grain size, texture, color, eye color, and bruchid-damaged grains on cowpea market prices. The data for the...
